Deferred income tax and social contribution represented by deferred tax assets and liabilities is obtained based on the differences between the tax bases of assets and liabilities and the amounts reported in the financial statements at each year end. Deferred tax assets are only recognized when it is probable that future taxable income will be available for offsetting. The Income Tax and Social Contribution expense is recognized in the Consolidated Statement of Income under Income Tax and Social Contribution, except when it refers to items directly recognized in Stockholders’ Equity, such as tax on marking available-for-sale financial assets to market, post-employment benefits and tax on cash flow hedges and hedge of net investment in foreign operations.

The defined benefit obligation is calculated annually by an independent actuarial consulting company using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated amount of future cash flows of benefit payments at the rate for Brazilian treasury long term securities denominated in Reais and with maturity periods similar to the term of the pension plan liabilities. Pension plans - defined contribution For defined contribution plans, contributions to plans made by ITAÚ UNIBANCO HOLDING PRUDENTIAL, through pension plan funds, are recognized as expenses when due.

The Income Tax and Social Contribution expense is recognized in the Consolidated Statement of Income under Income Tax and Social Contribution, except when it refers to items directly recognized in Stockholders’ Equity, such as tax on marking available-for-sale financial assets to market, post-employment benefits and tax on cash flow hedges and hedge of net investment in foreign operations. Subsequently, these items are recognized in income together with the recognition of the gain/loss originally deferred. Changes in tax legislation and rates are recognized in the Consolidated statement of income under Income tax and social contribution in the period in which they are enacted. Interest and fines are recognized in the consolidated statement of income under Other administrative expenses. Tax rates, as well as their calculation bases, are detailed in Note 10. p) Deferred income – this refers to: (i) interest received in advance on which there is no prospect of demand for payment and which depends only on the passage of time to be appropriated to effective income, and (ii) the negative goodwill on acquisition of investments, which has not been absorbed in the consolidation process. q) Post-employments benefits Pension plans - defined benefit plans The liability (or asset, as the case may be) recognized in the consolidated balance sheet with respect to a defined benefit plan corresponds to the present value of the defined benefit obligations on the balance sheet date less the fair value of the plan assets. The defined benefit obligation is calculated annually by an independent actuarial consulting company using the projected unit credit method. The present value of the defined benefit obligation is determined by discounting the estimated amount of future cash flows of benefit payments at the rate for Brazilian treasury long term securities denominated in Reais and with maturity periods similar to the term of the pension plan liabilities. Pension plans - defined contribution For defined contribution plans, contributions to plans made by ITAÚ UNIBANCO HOLDING PRUDENTIAL, through pension plan funds, are recognized as expenses when due. Other post-employment benefit obligations These obligations are assessed annually by independent, qualified actuaries, and the costs expected from these benefits are accrued over the period of employment. Gains and losses arising from changes in practices and variations in actuarial assumptions are recognized in stockholders’ equity in Equity valuation adjustment in the period in which they occur. r) Foreign currency translation I - Functional and presentation currency The Consolidated Financial Statements of ITAÚ UNIBANCO HOLDING PRUDENTIAL are presented in Brazilian Reais, its functional and presentation currency. For each subsidiary, joint venture or investment in an associates, ITAÚ UNIBANCO HOLDING PRUDENTIAL defines the functional currency as the currency of the primary economic environment in which the entity operates. II - Foreign Currency Transactions Foreign currency transactions are translated using the exchange rates prevailing on the dates of the transactions. Foreign exchange gains and losses are recognized in the Consolidated Statement of Income, unless they are related to cash flow hedges, which are recognized in Stockholders' Equity.

f) Derivative financial Instruments ITAÚ UNIBANCO HOLDING PRUDENTIAL trades in derivative financial instruments with various counterparties to manage its overall exposures and to assist its customers in managing their own exposures. Futures – Interest rate and foreign currency futures contracts are commitments to buy or sell a financial instrument at a future date, at an agreed price or yield, and may be settled in cash or through delivery. The notional amount represents the face value of the underlying instrument. Commodity futures contracts or financial instruments are commitments to buy or sell commodities (mainly gold, coffee and orange juice) at a future date, at an agreed price, which are settled in cash. The notional amount represents the quantity of such commodities multiplied by the future price on the contract date. Daily cash settlements of price movements are made for all instruments. Forwards – Interest rate forward contracts are agreements to exchange payments on a specified future date, based on the variation in market interest rates from trade date to contract settlement date. Foreign exchange forward contracts represent agreements to exchange the currency of one country for the currency of another at an agreed price, on an agreed settlement date. Financial instrument forward contracts are commitments to buy or sell a financial instrument on a future date at an agreed price and are settled in cash. Swaps – Interest rate and foreign exchange swap contracts are commitments to settle in cash on a future date or dates the differentials between specific financial indices (either two different interest rates in a single currency or two different rates each in a different currency), as applied to a notional principal amount. Swap contracts shown under Other in the table below correspond substantially to inflation rate swap contracts. Options – Option contracts give the purchaser, for a fee, the right, but not the obligation, to buy or sell a financial instrument within a limited time, including a flow of interest, foreign currencies, commodities, or financial instruments at an agreed price that may also be settled in cash, based on the differential between specific indices. Credit Derivatives – Credit derivatives are financial instruments with value deriving from the credit risk on debt issued by a third party (the reference entity), which permits one party (the buyer of the hedge) to transfer the risk to the counterparty (the seller of the hedge). The seller of the hedge must pay out as provided for in the contract if the reference entity undergoes a credit event, such as bankruptcy, default or debt restructuring. The seller of the hedge receives a premium for the hedge but, on the other hand, assumes the risk that the underlying instrument referenced in the contract undergoes a credit event, and the seller may have to make payment to the purchaser of the hedge for up to the notional amount of the credit derivative. ITAÚ UNIBANCO HOLDING PRUDENTIAL buys and sells credit protection in order to meet the needs of its customers, management and mitigation of its portfolios' risk. CDS (credit default swap) is credit derivative in which, upon a default related to the reference entity, the protection buyer is entitled to receive, from the protection seller, the amount equivalent to the difference between the face value of the CDS contract and the fair value of the liability on the date the contract was settled, also known as the recovered amount. The protection buyer does not need to hold the debt instrument of the reference entity for it to receive the amounts due pursuant to the CDS contract terms when a credit event occurs. TRS (total return swap) is a transaction in which a party swaps the total return of an asset or of a basket of assets for regular cash flows, usually interest and a guarantee against capital loss. In a TRS contract, the parties do not transfer the ownership of the assets. The total value of margins pledged in guarantee by ITAÚ UNIBANCO HOLDING PRUDENTIAL was R$ 12,198,045 (R$ 10,048,165 at 12/31/2018) and was basically comprised of government securities.

Note 8 – Contingent Assets and Liabilities, Provisions and Legal Obligations In the ordinary course of its business, ITAÚ UNIBANCO HOLDING PRUDENTIAL may be a party to legal proceedings to labor, civil and tax nature. The contingencies related to these lawsuits are classified as follows: a) Contingent Assets: There are no contingent assets recorded. b) Provisions and contingencies: The criteria to quantify of provisions for contingencies are adequate in relation to the specific characteristics of civil, labor and tax lawsuits portfolios, as well as other risks, taking into consideration the opinion of its legal advisors, the nature of the lawsuits, the similarity with previous lawsuits and the prevailing previous court decisions. A provision is recognized whenever the loss is classified as probable. Legal liabilities arise from lawsuits filed to discuss the legality and unconstitutionality of the legislation in force, being subject to an accounting provision. I- Civil lawsuits: In general, provisions and contingencies arise from claims related to the revision of contracts and compensation for material and moral damages. The lawsuits are classified as follows: Collective lawsuits: Related to claims of a similar nature and with individual amounts that are not considered significant. Provisions are calculated on a monthly basis and the expected amount of losses is accrued according to statistical references that take into account the nature of the lawsuit and the characteristics of the court (Small Claims Court or Regular Court). Contingencies and provisions are adjusted to reflect the amounts deposited into court as guarantee for their execution when realized. Individual lawsuits: Related to claims with unusual characteristics or involving significant amounts. The probability of loss is ascertained periodically, based on the amount claimed and the special nature of each case. The amounts considered as probable losses are recorded as provisions. ITAÚ UNIBANCO HOLDING PRUDENTIAL, despite having complied with the rules in force at the time, is a defendant in lawsuits filed by individuals referring to payment of inflation adjustments to savings accounts resulting from economic plants implemented in the 1980s and the 1990s, as well as in collective lawsuits filed by: (i) consumer protection associations; and (ii) the Public Attorney’s Office, on behalf of the savings accounts holders. ITAÚ UNIBANCO HOLDING PRUDENTIAL recognizes provisions upon receipt of summons, and when individuals demand the enforcement of a ruling handed down by the courts, using the same criteria as for provisions for individual lawsuits. The Federal Supreme Court (STF) has issued some decisions favorable to savings account holders, but it has not established its understanding with respect to the constitutionality of the economic plans and their applicability to savings accounts. Currently, the appeals involving these matters are suspended, by order of the STF, until it pronounces its final decision. In December 2017, through mediation of the Federal Attorney’s Office (AGU) and supervision of the BACEN, savers (represented by two civil associations, FEBRAPO and IDEC) and FEBRABAN entered into an instrument of agreement aiming at resolving lawsuits related to economic plans, and ITAÚ UNIBANCO HOLDING PRUDENTIAL has already accepted its terms. The agreement was approved on March 1, 2018, by the Plenary Session of the Federal Supreme Court (STF), with the legal actions accordingly being cancelled. Savers have 24 months from May 22, 2018 to accept the settlement. Itaú Unibanco Holding S.A. – Demonstrações Contábeis Prudencial – 31 de Dezembro de 2019 4.39 Note 8 – Contingent Assets and Liabilities, Provisions and Legal Obligations In the ordinary course of its business, ITAÚ UNIBANCO HOLDING PRUDENTIAL may be a party to legal proceedings to labor, civil and tax nature. The contingencies related to these lawsuits are classified as follows: a) Contingent Assets: There are no contingent assets recorded. b) Provisions and contingencies: The criteria to quantify of provisions for contingencies are adequate in relation to the specific characteristics of civil, labor and tax lawsuits portfolios, as well as other risks, taking into consideration the opinion of its legal advisors, the nature of the lawsuits, the similarity with previous lawsuits and the prevailing previous court decisions. A provision is recognized whenever the loss is classified as probable. Legal liabilities arise from lawsuits filed to discuss the legality and unconstitutionality of the legislation in force, being subject to an accounting provision. I- Civil lawsuits: In general, provisions and contingencies arise from claims related to the revision of contracts and compensation for material and moral damages. The lawsuits are classified as follows: Collective lawsuits: Related to claims of a similar nature and with individual amounts that are not considered significant. Provisions are calculated on a monthly basis and the expected amount of losses is accrued according to statistical references that take into account the nature of the lawsuit and the characteristics of the court (Small Claims Court or Regular Court). Contingencies and provisions are adjusted to reflect the amounts deposited into court as guarantee for their execution when realized. Individual lawsuits: Related to claims with unusual characteristics or involving significant amounts. The probability of loss is ascertained periodically, based on the amount claimed and the special nature of each case. The amounts considered as probable losses are recorded as provisions. ITAÚ UNIBANCO HOLDING PRUDENTIAL, despite having complied with the rules in force at the time, is a defendant in lawsuits filed by individuals referring to payment of inflation adjustments to savings accounts resulting from economic plants implemented in the 1980s and the 1990s, as well as in collective lawsuits filed by: (i) consumer protection associations; and (ii) the Public Attorney’s Office, on behalf of the savings accounts holders. ITAÚ UNIBANCO HOLDING PRUDENTIAL recognizes provisions upon receipt of summons, and when individuals demand the enforcement of a ruling handed down by the courts, using the same criteria as for provisions for individual lawsuits. The Federal Supreme Court (STF) has issued some decisions favorable to savings account holders, but it has not established its understanding with respect to the constitutionality of the economic plans and their applicability to savings accounts. Currently, the appeals involving these matters are suspended, by order of the STF, until it pronounces its final decision. In December 2017, through mediation of the Federal Attorney’s Office (AGU) and supervision of the BACEN, savers (represented by two civil associations, FEBRAPO and IDEC) and FEBRABAN entered into an instrument of agreement aiming at resolving lawsuits related to economic plans, and ITAÚ UNIBANCO HOLDING PRUDENTIAL has already accepted its terms. The agreement was approved on March 1, 2018, by the Plenary Session of the Federal Supreme Court (STF), with the legal actions accordingly being cancelled. Savers have 24 months from May 22, 2018 to accept the settlement. Itaú Unibanco Holding S.A. – Demonstrações Contábeis Prudencial – 31 de Dezembro de 2019 4.39

II- Labor claims Provisions for contingencies arise from lawsuits in which labor rights provided for in labor legislation specific to the related profession are discussed, such as: overtime, salary equalization, reinstatement, transfer allowance and, pension plan supplement. These lawsuits are classified as follows: Collective lawsuits: related to claims considered similar and with individual amounts that are not considered significant. The expected amount of loss is determined and accrued on a monthly basis in accordance with a statistical model which calculates the amount of the claims, and is reassessed taking into account court rulings. Provisions for contingencies are adjusted to reflect the amounts deposited into court as security for execution. Individual lawsuits: related to claims with unusual characteristics or involving significant amounts. These are periodically calculated based on the amounts claimed. The probability of loss is estimated in accordance with the actual and legal characteristics of each lawsuit. III- Other Risks These are quantified and accrued on the basis of the value of rural credit transactions with joint liability and FCVS (salary variations compensation fund) credits assigned to Banco Nacional.

Note 14 - Market value In cases where market prices are not available, market value are based on estimates using discounted cash flows or other valuation techniques. These techniques are significantly affected by the assumptions adopted, including the discount rate and estimate of future cash flows.

However, not all instruments have liquidity or quoted market prices and, in such cases, it is necessary to adopt present value estimates and other pricing techniques to establish their market value. In the absence of the prices quoted by the Brazilian Financial and Capital Markets Association (ANBIMA), the market values of government securities are determined based on the interest rates provided by brokers. The market values of corporate debt securities are calculated by discounting estimated cash flows at market interest rates. The market values of shares are computed based on their prices quoted in the market. The market values of derivative financial instruments were determined as follows: · Swaps: Their cash flows are discounted to present value based on yield curves that reflect the appropriate risk factors, drawn mainly based on the exchange price of derivatives at B3, of Brazilian government securities in the secondary market or derivatives and securities traded abroad. These yield curves may be used to obtain the market value of currency swaps, interest rate swaps and swaps based on other risk factors (commodities, stock exchange indices, etc.) · Futures and Forwards: Quotations on exchanges or using criteria identical to those applied to swaps. · Options: determined based on mathematical models, such as Black & Scholes, using data, in general from Bloomberg, of implicit volatility, interest rate yield curve and market value of the underlying asset. Current market prices of options are used to compute the implicit volatilities. · Credit Derivatives: inversely related to the probability of default (PD) in a financial instrument subject to credit risk. The process of adjusting the market price of these spreads is based on the differences between the yield curves with and without credit risk.

d) Loan operations and lease operations and other credits – Market value is estimated based on groups of loans with similar financial and risk characteristics, using valuation models. The market value of fixed-rate loans was determined by discounting estimated cash flows, applying current interest rates close of similar loans. For the majority of loans at floating rate, the carrying amount was considered close to their market value. The market value of loan and lease operations not overdue was calculated by discounting the expected payments of principal and interest through maturity. The market value of overdue loan and lease transactions was based on the discount of estimated cash flows, using a rate proportional to the risk associated with the estimated cash flows, or on the underlying collateral. The assumptions related to cash flows and discount rates are determined using information available in the market and information specific of the debtor.

a) Main Actuarial Assumptions Actuarial assumptions of demographic and financial nature should reflect the best estimated about the variables that determine the post-employment benefit obligations. The main demographic assumptions comprise: mortality table and turnover of active participants and the main financial assumptions include: discount rate, future salary increases, growth of plan benefits and inflation. 12/31/2019 12/31/2018 (1) Discount rate 7.64% p.a. 9.72% p.a.

Growth of the pension fund benefits 4.00 % p.a. 4.00 % p.a. Inflation 4.00 % p.a. 4.00 % p.a. Actuarial method Projected Unit Credit Projected Unit Credit (1) Determined based on market yield related to National Treasury Notes (NTN-B) and compatible with the economic scenario observed on the balance sheet closing date, considering the volatility of interest market and models used. (2) Correspond to those disclosed by SOA – Society of Actuaries, that reflect a 10% increase in the probabilities of survival regarding the respective basic tables. (3) Updated to the new expectation of mass behavior. Retired plans sponsored by foreign subsidiaries - Banco Itaú (Suisse) S.A., Itaú CorpBanca Colombia S.A. and PROSERV - Promociones y Servicios S.A. de C.V. - are structured as Defined Benefit modality and adopt actual assumptions adequate to masses of participants and the economic scenario of each country. b) Risk Management The EFPCs sponsored by ITAÚ UNIBANCO HOLDING are regulated by the National Council for Complementary Pension (CNPC) and PREVIC, has an Executive Board, Advisory and Tax Councils. Benefits offered have long-term characteristics and the main factors involved in the management and measurement of their risks are financial risk, inflation risk and biometric risk. - Financial Risk – the actuarial liability is calculated by adopting a discount rate different from rates earned in investments. If real income from plan investments is lower than yield expected, this may give rise to a deficit. To mitigate this risk and assure the capacity to pay long-term benefits, the plans have a significant percentage of fixed-income securities pegged to the plan commitments, aiming at minimizing volatility and risk of mismatch between assets and liabilities. - Inflation risk – a large part of liabilities is pegged to inflation risk, making actuarial liabilities sensitive to increase in rates. To mitigate this risk, the same financial risks mitigation strategies are used. - Demographic Risk – plans that have any obligation actuarially assessed are exposed to biometric risk. In the event the mortality tables used are not adherent to the mass of plan participants, a deficit or surplus may arise in actuarial evaluation. To mitigate this risk, adherence tests to biometric assumptions are conducted to ensure their adequacy to liabilities of respective plans. For purposes of registering in the balance sheet the EFPCs that manage them, actuarial liabilities of plans use discount rate adherent to its asset portfolio and income and expense flows, according to a study prepared by an independent consulting company. The actuarial method used is the aggregate method, through which the plan costing Is defined by the difference between its equity coverage and the current value of its future liabilities. Observing the methodology established in the respective actuarial technical note. In the event deficit is verified in the concession period above the settlement limits set forth by the legislation in force, a debt agreement is entered into with the sponsor with financial guarantees.

(3) Updated to the new expectation of mass behavior. Retired plans sponsored by foreign subsidiaries - Banco Itaú (Suisse) S.A., Itaú CorpBanca Colombia S.A. and PROSERV - Promociones y Servicios S.A. de C.V. - are structured as Defined Benefit modality and adopt actual assumptions adequate to masses of participants and the economic scenario of each country. b) Risk Management The EFPCs sponsored by ITAÚ UNIBANCO HOLDING are regulated by the National Council for Complementary Pension (CNPC) and PREVIC, has an Executive Board, Advisory and Tax Councils. Benefits offered have long-term characteristics and the main factors involved in the management and measurement of their risks are financial risk, inflation risk and biometric risk. - Financial Risk – the actuarial liability is calculated by adopting a discount rate different from rates earned in investments. If real income from plan investments is lower than yield expected, this may give rise to a deficit. To mitigate this risk and assure the capacity to pay long-term benefits, the plans have a significant percentage of fixed-income securities pegged to the plan commitments, aiming at minimizing volatility and risk of mismatch between assets and liabilities. - Inflation risk – a large part of liabilities is pegged to inflation risk, making actuarial liabilities sensitive to increase in rates. To mitigate this risk, the same financial risks mitigation strategies are used. - Demographic Risk – plans that have any obligation actuarially assessed are exposed to biometric risk. In the event the mortality tables used are not adherent to the mass of plan participants, a deficit or surplus may arise in actuarial evaluation. To mitigate this risk, adherence tests to biometric assumptions are conducted to ensure their adequacy to liabilities of respective plans. For purposes of registering in the balance sheet the EFPCs that manage them, actuarial liabilities of plans use discount rate adherent to its asset portfolio and income and expense flows, according to a study prepared by an independent consulting company. The actuarial method used is the aggregate method, through which the plan costing Is defined by the difference between its equity coverage and the current value of its future liabilities. Observing the methodology established in the respective actuarial technical note. In the event deficit is verified in the concession period above the settlement limits set forth by the legislation in force, a debt agreement is entered into with the sponsor with financial guarantees.

Based on this statement, five dimensions have been defined (Capitalization, Liquidity, Composition of Earnings, Operating Risk and Reputation). Each dimension consists of a set of metrics associated with the main risks involved, combining supplementary measurement methods, to give a comprehensive vision of our exposure. The Board of Directors is responsible for approving guidelines and limits for risk appetite, with the support of CGRC and the CRO (Chief Risk Officer). The limits for risk appetite are monitored regularly and reported to risk committees and to the Board of Directors, which will oversee the preventive measures to be taken to ensure that exposure is aligned with the strategies of ITAÚ UNIBANCO HOLDING CONSOLIDATED. Foremost among BACEN’s requirements for proper risk and capital management are the Risk Appetite Statement (RAS) and the implementation of a continuous, integrated risk management structure, the stress test program, the establishment of a Risk Committee, and the nomination at BACEN of a Chief Risk Officer (CRO), with roles and responsibilities assigned, and requirements for independence. Risk appetite, risk management and guidelines for employees of ITAÚ UNIBANCO HOLDING CONSOLIDATED for routine decision-making purposes are based on: · Sustainability and customer satisfaction: ITAÚ UNIBANCO HOLDING CONSOLIDATED’s vision is to be the leading bank in sustainable performance and customer satisfaction and, accordingly, we are committed to creating shared value for staff, customers, stockholders and society, ensuring the continuity of the business. ITAÚ UNIBANCO HOLDING CONSOLIDATED is committed to doing business that is good both for the customer and the institution itself; · Risk Culture: ITAÚ UNIBANCO HOLDING CONSOLIDATED’s risk culture goes beyond policies, procedures or processes, reinforcing the individual and collective responsibility of all employees so that they will do the right thing at the right time and in the proper manner, respecting the ethical way of doing business; · Risk pricing: ITAÚ UNIBANCO HOLDING CONSOLIDATED’s acts and assumes risks in business which it knows and understands, avoiding those with which it is unfamiliar or that do not offer a competitive edge, and carefully assessing the risk-return ratio; · Diversification: ITAÚ UNIBANCO HOLDING CONSOLIDATED has little appetite for volatility in earnings, and it therefore operates with a diverse base of customers, products and business, seeking to diversify risks and giving priority to lower risk business; · Operational excellence: It is the wish of ITAÚ UNIBANCO HOLDING CONSOLIDATED to be an agile bank, with a robust and stable infrastructure enabling us to offer top quality services; · Ethics and respect for regulation: for ITAÚ UNIBANCO HOLDING CONSOLIDATED, ethics is non- negotiable, and it therefore promotes an institutional environment of integrity, encouraging staff to cultivate ethics in relationships and business and to respect the rules, thus caring for the institution’s reputation.

These principles serve as a basis for ITAÚ UNIBANCO HOLDING CONSOLIDATED’s guidelines, helping employees to conscientiously understand, identify, measure, manage and mitigate risks. I – Credit risk The possibility of losses arising from failure by a borrower, issuer or counterparty to meet their financial obligations, the impairment of a loan due to downgrading of the risk rating of the borrower, the issuer or the counterparty, a decrease in earnings or remuneration, advantages conceded on renegotiation or the costs of recovery.

The credit policy of ITAÚ UNIBANCO HOLDING CONSOLIDATED is based on internal criteria such as: classification of customers, portfolio performance and changes, default levels, rate of return and economic capital allocated, and external factors such as interest rates, market default indicators, inflation, changes in consumption, and so on. In compliance with CMN Resolution 4,557, of February 23, 2017, the document “Public Access Report – Credit Risk”, which includes the guidelines established by our credit risk control policy, can be viewed at www.itau.com.br/investor-relations, under Corporate Governance, Rules and Policies, Reports. II - Market risk The possibility of incurring financial losses from changes in the market value of positions held by a financial institution, including the risks of transactions subject to fluctuations in currency rates, interest rates, share prices, price indexes and commodity prices. ITAÚ UNIBANCO HOLDING CONSOLIDATED’s market risk management strategy is aimed at balancing corporate business goals, taking into account, among other things, political, economic and market conditions, the portfolio profile and the ability to operate in specific markets. Market risk is controlled by an area independent from the business areas, which is responsible for the daily activities of (i) risk measurement and assessment, (ii) monitoring of stress scenarios, limits and alerts, (iii) application, analysis and testing of stress scenarios, (iv) risk reporting to those responsible within the business areas, in compliance with the governance of ITAÚ UNIBANCO HOLDING CONSOLIDATED, (v) monitoring of actions required to adjust positions and risk levels to make them realistic, and (vi) providing support for the safe launch of new financial products. The National Monetary Council (CMN) has regulations governing the segregation of exposure to market risk into risk factors, such as: interest rate, exchange rate, equities and commodities. Brazilian inflation indexes are treated as a group of risk indicators and limits are managed in the same way as for the other indicators. The structure of limits and alerts obeys the Board of Directors’ guidelines, and it is reviewed and approved on an annual basis. This structure has specific limits aimed at improving the process of monitoring and understanding risk, and at avoiding concentration. These limits are quantified by assessing the forecast balance sheet results, the size of stockholders’ equity, market liquidity, complexity and volatility, and the institution’s appetite for risk. In order to operate within the defined limits, ITAÚ UNIBANCO HOLDING CONSOLIDATED hedges transactions with customers and proprietary positions, including its foreign investments. Derivatives are commonly used for these hedging activities, which can be either accounting or economic hedges, both governed by the institutional polices of ITAÚ UNIBANCO HOLDING CONSOLIDATED (Note 5 – Securities and derivative financial instruments). The market risk structure categorizes transactions as part of either the banking portfolio or the trading portfolio, in accordance with general criteria established by CMN Resolution 4,557, of February 23, 2017, and BACEN Circular 3,354, of June 27, 2007. The trading portfolio consists of all transactions involving financial instruments and commodities, including derivatives, which are held for trading. The banking portfolio is basically characterized by transactions for the banking business, and transactions related to the management of the balance sheet of the institution, where there is no intention of sale and time horizons are medium and long term. Market risk management is based on the following metrics: · Value at risk (VaR): a statistical measure that estimates the expected maximum potential economic loss under normal market conditions, considering a certain time horizon and confidence level; · Losses in stress scenarios: simulation technique to assess the behavior of assets, liabilities and derivatives of a portfolio when several risk factors are taken to extreme market situations (based on prospective and historical scenarios); · Stop loss: metrics used to revise positions, should losses accumulated in a fixed period reach a certain level; · Concentration: cumulative exposure of a certain financial instrument or risk factor, calculated at market value (MtM – Marked to Market); and Itaú Unibanco Holding S.A. – Demonstrações Contábeis Prudencial – 31 de Dezembro de 2019 4.68 The credit policy of ITAÚ UNIBANCO HOLDING CONSOLIDATED is based on internal criteria such as: classification of customers, portfolio performance and changes, default levels, rate of return and economic capital allocated, and external factors such as interest rates, market default indicators, inflation, changes in consumption, and so on.

These limits are quantified by assessing the forecast balance sheet results, the size of stockholders’ equity, market liquidity, complexity and volatility, and the institution’s appetite for risk. In order to operate within the defined limits, ITAÚ UNIBANCO HOLDING CONSOLIDATED hedges transactions with customers and proprietary positions, including its foreign investments. Derivatives are commonly used for these hedging activities, which can be either accounting or economic hedges, both governed by the institutional polices of ITAÚ UNIBANCO HOLDING CONSOLIDATED (Note 5 – Securities and derivative financial instruments). The market risk structure categorizes transactions as part of either the banking portfolio or the trading portfolio, in accordance with general criteria established by CMN Resolution 4,557, of February 23, 2017, and BACEN Circular 3,354, of June 27, 2007. The trading portfolio consists of all transactions involving financial instruments and commodities, including derivatives, which are held for trading. The banking portfolio is basically characterized by transactions for the banking business, and transactions related to the management of the balance sheet of the institution, where there is no intention of sale and time horizons are medium and long term. Market risk management is based on the following metrics: · Value at risk (VaR): a statistical measure that estimates the expected maximum potential economic loss under normal market conditions, considering a certain time horizon and confidence level; · Losses in stress scenarios: simulation technique to assess the behavior of assets, liabilities and derivatives of a portfolio when several risk factors are taken to extreme market situations (based on prospective and historical scenarios); · Stop loss: metrics used to revise positions, should losses accumulated in a fixed period reach a certain level; · Concentration: cumulative exposure of a certain financial instrument or risk factor, calculated at market value (MtM – Marked to Market); and Itaú Unibanco Holding S.A. – Demonstrações Contábeis Prudencial – 31 de Dezembro de 2019 4.68

· Stressed VaR: statistical metric derived from the VaR calculation, with the purpose is of simulating higher risk in the trading portfolio, taking returns that can be seen in past scenarios of extreme volatility. Management of interest rate risk in the Banking Book (IRRBB) is based on the following metrics: · ΔEVE (Delta Economic Value of Equity): difference between the present value of the sum of repricing flows of instruments subject to IRRBB in a base scenario and the present value of the sum of repricing flows of these instruments in a scenario of interest rate shock; · ΔNII (Delta Net Interest Income): difference between the result of financial intermediation of instruments subject to IRRBB in a base scenario and the result of financial intermediation of these instruments in a scenario of shock in interest rates. In addition, sensitivity and loss control measures are also analyzed. They include: · Mismatching analysis (GAPS): accumulated exposure by risk factor of cash flows expressed at market value, allocated at the maturity dates; · Sensitivity (DV01- Delta Variation): impact on the market value of cash flows, when submitted to an one annual basis point increase in the current interest rates or index rate; · Sensitivity to Sundry Risk Factors (Greeks): partial derivatives of an option portfolio in relation to the prices of underlying assets, implied volatilities, interest rates and time. ITAÚ UNIBANCO HOLDING CONSOLIDATED uses proprietary systems to measure the consolidated market risk. The processing of these systems occurs in a high-availability access-controlled environment, which has data storage and recovery processes and an infrastructure that ensures business continuity in contingency (disaster recovery) situations. At December 31, 2019, ITAÚ UNIBANCO HOLDING CONSOLIDATED showed Total VaR of R$ 278.3 million, a reduction in relation to the same period of the previous year (R$ 381.5 million at December 31, 2018), due to lower exposure in interest rates.

III – Liquidity risk The possibility that the institution may be unable to efficiently meet its expected and unexpected obligations, both current and future, including those arising from guarantees issued, without affecting its daily operations and without incurring significant losses. Liquidity risk is controlled by an area independent from the business area and responsible for establishing the reserve composition, estimating the cash flow and exposure to liquidity risk in different time horizons, and for monitoring the minimum limits to absorb losses in stress scenarios for each country where ITAÚ UNIBANCO HOLDING CONSOLIDATED operates. All activities are subject to verification by independent validation, internal control and audit areas.

IV – Operating risk The possibility of losses from failures, defects or shortcomings in internal processes, people or systems, or from external events impacting the realization of strategic, tactical or operational objectives. It includes the legal risk of inadequacies or defects in agreements signed by the institution, as well as sanctions for failing to comply with legal provisions and compensation to third parties for losses arising from the institution’s activities.

The Board is also responsible for the full approval of the ICAAP (Internal Capital Adequacy Assessment Process) report, the purpose of which is to assess the capital adequacy of ITAÚ UNIBANCO HOLDING CONSOLIDATED. The result of the last ICAAP – which was dated December 2018 – indicated that ITAÚ UNIBANCO HOLDING CONSOLIDATED has, in addition to capital to cover all material risks, a significant capital surplus, thus assuring the solidity of the institution’s equity position.

Reasonable assurance is a high level of assurance, but is not a guarantee that the audit conducted in accordance with the Brazilian and International Standards on Auditing will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements. As part of an audit in accordance with Brazilian and International Standards on Auditing, taking into consideration the NBC TA 800 (Special Conditions – Audit Financial Statements in accordance with special purpose accounting conceptual structures), we exercise professional judgment and maintain professional skepticism throughout the audit. We also: • Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. • Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the internal control of the Bank and its subsidiaries. • Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management. • Conclude on the appropriateness of management's use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Bank's ability to continue as going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor's report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor's report. However, future events or conditions may cause the Bank to cease to continue as going concern. • Evaluate the overall presentation, structure and content of the consolidated financial statements, including the disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.
